[Xen-users] Bridge with Xen-interfaces only doesn''t work
Hi, maybe it''s a well-known problem already. So the problem is: I have 2 bridges: xenbr0 and xenbr1 The bridges are prepared on startup. xenbr1 contains eth0, xenbr1 contains _no_ interface. "brctl show" looks like this: # brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.001617b458ff no eth0 xenbr1 8000.000000000000 no As you can see, xenbr1 has no mac-address. xenbr0 has "inherited" the mac-address of eth0 (namely 00:16:17:B4:58:FF). xenbr1 will have a mac-address, when xend adds the first interface to the interface. The mac-address of the xen-interfaces (on dom0-side) is usually something like FE:FF:FF:FF:FF:FF. xenbr0 as well as xenbr1 have an IP. The problem: Somehow the Network between domUs and dom0 doesn''t work. ping works, but TCP/IP doesn''t. Workaround: I create a tun-interface and add it to xenbr1. Then everything works! Is this a known problem? Any clue, how i could workaround the problem more easily than creating a unused tun-interface?
